Objective
DXC+DX12 debug builds with an environment map have been broken since #11366 merged due to an internal compiler error in DXC. I tracked it down to a single
break
statement and reported it upstream (microsoft/DirectXShaderCompiler#6183)Solution
Workaround the ICE by setting the for loop index variable to the max value of the loop to avoid the
break
that's causing the ICE.This works because it's the last thing in the for loop.
The
reflection_probes
andpbr
examples both appear to still work correctly.
